I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Take heart, Goldilocks -- and get more sleep

Sleeping too little or too much increases the risk of cardiovascular events and death in those with coronary artery disease, according to a new paper from Emory Clinical Cardiovascular Research Institute. Others have observed a similar U-shaped risk curve in the general population, with respect to sleep duration. The new study, published in American Journal of Cardiology, extends the finding to people who were being evaluated for coronary artery disease. Arshed Quyyumi, MD and colleagues analyzed Read more

Exotic immune systems are big business

What timing! Just when our feature on Max Cooper and lamprey immunology was scheduled for publication, the Japan Prize Foundation announced it would honor Cooper and his achievements.

Cooper was one of the founders of modern immunology. We connect his early work with his lab’s more recent focus on lampreys, primitive parasites with surprisingly sophisticated immune systems.

Molecules from animals with exotic immune systems can be big business, as Andrew Joseph from STAT News points out. Pharmaceutical giant Sanofi recently bought a company focused on nanobodies, originally derived from camels, llamas and alpacas, for $4.8 billion.

Lampreys’ variable lymphocyte receptors (VLRs) are their version of antibodies, even though they look quite different in molecular terms. Research on VLRs and their origins may seem impractical. However, Cooper’s team has shown their utility as diagnostic tools, and his colleagues have been weaponizing them, possibly for use in cancer immunotherapy.

CAR-T cells have attracted attention for dramatic elimination of certain types of leukemias from the body and also for harsh side effects and staggering costs; see this opinion piece by Georgia Tech’s Aaron Levine. Now many research teams are scheming about how to apply the approach to other types of cancers. The provocative idea is: replace the standard CAR (chimeric antigen receptor) warhead with a lamprey VLR.
